New Materials For Stainless Steel Turning

Sumitomo Electric has developed new materials, AC6030M/AC6040M, and the EM breaker for rough cutting, all for use in cutting tools for turning stainless steel. They provide stability and long tool life for processing ranging from general cutting to interrupted cutting of stainless steel. These products go on sale in November 2014.

Sumitomo developed the new EM model for rough cutting to complement the existing EG model for medium cutting of stainless steel and EF model for finishing, producing a series of stainless steel processing breakers. The newly developed EM breaker for rough cutting maintains sharpness with excellent strength at the cutting edge. Smooth control of chips during rough processing prevents chipping of the cutting edge caused by these fragments, resulting in more stable processing of stainless steel.
